COOLING APPARATUS.

Specification of Letters Patent.

Application filed 0ctober28, 1907.

Patented Apr. 19, 1910.

Serial No. 399,490.

and HnNirY lVIsE, citizens of the United States, resldmg at Wooster, inthe county of Wayne and State of Ohio, and at Cleveland, in the countyof Cuyahoga and State of Ohio, respectively, have invented certain newand useful Improvements in Cooling Apparatus, of which the following isa specification.

Our invention relates to improvements in cooling apparatus beingdesigned with special reference for use in connection withdispensing-cabinets and soda-fountains used in dispensing carbonatedbeverages.

The primary object of the invention is to provide a generally-improvedcooling means adapted to produce and utilize a maximum amount of coldair with a minimum consumption of ice, the main cooling chamber orice-chest, in the present instance, being centrally located withreference to the storage-chambers, and provided at its upper portionwith an ice-receiving-hopper intermediate the syrup-containers, and withlaterally-extending compartments leading to and about saidsyrup-containers, with openings in the sides of saidice-receiving-hopper and ice-chest providing for a free circulation ofair to and from said laterally-extending compartments.

'With the above mentioned and other objects in view, the inventionconsists in the novel construction, arrangement and combination ofparts, hereinafter described, illustrated in the accompanying'drawings,and particularly pointed out in the appended claims.

Referring to the drawings, Figure 1, is a rear elevation of a form ofcooling apparatus embodying our invention. Flg. 2, a horizontallongitudinal sectional view taken through line 2-2, of Fig. 1. Fig. 3, avertical longitudinal sectional view taken through line 33, of Fig. 2,with the main or central cooling-chamber filled with ice. Fig. 4, atransverse vertical sectional view taken through line -1-4, of Fig. 1.

Similar characters of reference designate like parts throughout all thefigures of the drawings.

The present embodiment of the invention comprises a dispensing-cabinetand counter designed for use in dispensing carbonated beverages.

The face of the counter 1, and counter slab 2, may be of the usualconstruction, the dispensing cabinet being adapted to be used inconjunction therewith at the rear thereof, and comprising theindependent storage chambers 3, at the ends and the main ,or centralintermediate coolingchamber 4.

The end boxes or icecream cabinets 5, forming the storage-chambers 3,may be of the usual construction, containing the usual storage orice-cream can 6, surrounded with ice in the conventional style. The maincooling-chamber 4, or main ice-containingreceptacle is formed by meansof an ice-chest or box 7, provided in its bottom 8, with a supplementalchamber 9, and is preferably provided with an inner or second wall 10,having a lining of copper or other suitable material, and aninsulating-material 11, of cork, mineral wool, or the like, interposedbetween said inner and outer walls 7 and 10, respectively. If desired,the walls of the ice-cream cabinets 5, may be similarly constructed andinsulated.

The carbonated water to be cooled is conducted through a main inlet-pipeA, and thence through a plurality of cooling-cylinders 12, arranged inthe supplemental chamber 9, and communicating with each other,alternately at each end, by means of small cross connecting-pipes 13,said cylinders 12, communicating with a plurality of crosspipes 14,above, arranged at the bottom of the ice-chest 7 by means of a smallpipe 15 (see Fig. 4) at the end of one of the cylinders 12, and leadingto the end of one of the cross-pipes 14, said cross-pipes 14, beingarranged above and extending at right angles to the cylinders 12, andcommunicating with each other by means of small crossconnecting-pipes16, arranged similar to the connecting pipes 13. The cross cooling pipes14, in the bottom of the ice-chest 7, form a piped bottom above thecooling cylinders 12, and their cross arrangement with respect to saidcooling-cylinders brings their exterlor surfaces into a more directcontact with the intervening cool air and thus imparts a higher degreeof refrigeration to the liquid passing therethrough than in anarrangement in which the upper cooling-pipes are arranged parallel toand in alinement with the lower cooling pipes or cylinders. The coolingpipes 14, are also believed to be better adapted to keep the ice fromcoming into direct contact with the cooling cyl inders below, arranged,in the present instance, in a supplemental chamber 9, said chamber beingdesigned to receive the drippings of water from the ice in saidice-chest 7, as well as utilize the salt-water from the ice-creamcabinets 5, as now described.

The supplemental chamber 9, is adapted not only to receive the ice-waterfrom the ice contained in the ice-chest 7, but to receive the salt-waterfrom the ice-cream cabinets 5, through the medium of drain-pipes 17,leading from the bottom portion of the cabinets 5, whereby the saltwateris not only effectually drained from said cabinets but is utilized bymingling with the water from the ice in the chest 7, and circulatingabout the cooling-cylinders 12, of the supple mental chamber 9. As ameans of keeping the cylinders 12, submerged in said ice and saltwaters, as well as keeping the same out of contact with the cross-pipes14, and ice above in the bottom portions of the chest 7, the drain-head18, (see Fig.4) of the wastepipe 19, is mounted just above the plane ofthe upper portions of the cylinders 12, and substantially in the sameplane with the bot tom 8, of the chest 7, and, it will be observed thatas the outlets of the drain-pipes 17, are near the bottom of thesupplemental chamber 9, the salt water will be conducted upwardly andover and about the cylinders 12, toward the drain or overflow head 18.

The upper portion of the main coolingchamber or ice-containingreceptacle 4, comprises an ice-receiving hopper 20, (see Fig. 3,) andlaterally-extending communicating compartments 21, provided withdownwardly and inwardly inclined bottoms 22, leading to the ice-chest 7,through openings 23, in the sides 24, of the hopper 20, and walls of theice-chest. The front and rear walls 25, and 26, respectively, form thefront and rear walls of the ice receiving-hopper 20, and compartments21, said front wall 25, being arranged at the rear of the counter-face1,

and preferably provided with insulation 25*, and said rear wall 26,being preferably, inclined rearwardly away from the rear edge of thecounter-slab 2, with its upper edge overhanging, the ends 27, of thecompartments 21, and the sides 24, of the hopper 20, being adapted totake under the counterslab 2.

Inclined container-shelves 28, preferably of galvanized wire-netting, orother foraminous material, are mounted in the laterallyextendingcompartments 21, connected to the front and rear walls 25 and 26, andends 27, and provided with openings 29, adapted to take over the loweror trap ends of the jars or containers 30, supported on said shelves 28,and inclined and resting against the inclined rear wall or slab 26. Theshelves 28, are further supported by means of Wire-netting 31, at therear of the containers 30, extending from the rear of the counter-slab2, and connected at its lower edge to the shelves 28. Dispensing-pumps32, are carried by the container-lids 33, and openings 34, in the sides24, of the hopper 20, above and at the rear of the shelves 28, andwire-netting 31, respectively, provide for circulation of cool air atall times to and from the icereceiving-hopper 20, andlaterally-extending compartments 21, and over and about the containers30. If desired, ice may be passed through the openings 34, over andalong the shelves 28, and wire netting 31, at the rear of the containers30. The openings 23, are formed in the walls of the hopper 20, and theice-chest 7, above the chutes 22, so that the ice may extend into thecompartments 21, and over the lower ends of the chutes 22, as shown mostclearly in Fig. 3, of the drawings, as well as providing at all timesfor the circulation of air between said compartments 21, and the maincooling-chamber 4.

From the foregoing description, taken in connection with theaccompanying drawings, the operation and advantages of our inventionwill be readily understood.

Having thus described our invention, without having to set forth all theforms in which it may be made or all the modes of its use, we declarethat what we claim and desire to secure by Letters Patent is,-

1. A cooling apparatus, comprising storage-cabinets, an intermediatecooling-chamber provided with a supplemental chamber below the plane ofthe bottom of said storage-cabinets and carrying a plurality ofcommunicating cooling-cylinders, and drain pipes leading from saidstorage cabinets to said supplemental chamber, and a plurality ofcommunicating cross-cooling-pipes arranged above said cooling-cylinders.
